SHE'S long been known as the girl-next-door pint-sized pop star, but all that could be set to change thanks to a new book that details Kylie Minogue's alleged teenage sex life.

'Kylie', written by Sean Smith, tells of a time that a 16-year-old Kylie got frisky with an 18-year-old college footballer at a drunken house party - proving that it may not have been Michael Hutchence who corrupted her.

Graphic designer Paolo Marcolin, who was 18 at the time of his fling with Kylie, was at a friend's house party in their home city of Melbourne when she showed up with some friends.

According to details in the Daily Mirror, after accidentally falling on her, Paolo soon found himself kissing the petite teen before taking her somewhere more private.

We started kissing and I remember I told her my name and she said she was called Kylie. She was fantastic and knew what she was doing. I shut my eyes and let her get on with it.

"My hands were wandering a bit. Out of the blue, she said, 'Do you want to go somewhere even more private?' Of course I agreed. It sounded great to me.

"She had no idea where she was going but eventually took me to the opposite side of the house. There were a few people catching taxis, so we walked round the corner to be out of sight - or so I thought," he continued.

"We started kissing and I remember I told her my name and she said she was called Kylie. She was fantastic and knew what she was doing. I shut my eyes and let her get on with it."

However, the pair soon realised that they were in full view of fellow party guests so they headed to a small workshop underneath the house where Paolo claims they began to have sex.

"We lay on the floor. It was freezing but I had enough alcohol in me not to notice. I was really enjoying myself because Kylie was so nice," he explained.

But the pair were soon interrupted by one of Paolo's friends, with him adding" "I couldn't see whether Kylie was as embarrassed as me, but she followed us outside."

Back inside the party Kylie apparently burst into tears and accused Paolo of "using" her.

"She was wailing, I asked for her number and that seemed to cheer her up a bit," he recalled.

The pair went on a date shortly afterwards but Paolo soon decided to call it off, and has no regrets whatsoever about doing so.

"I don't have any regrets about breaking up or missing out on being part of her career. I just don't think it would have worked," he said.

His claims have led author Sean to suggest that perhaps INXS frontman Michael wasn't the one who influenced Kylie when it came to the bedroom.

"She may even have taught him a thing or two between the sheets. His boast that Kylie was the best f*** in the world doesn't seem quite so incredible," he writes in his book.

"Kylie clearly has always enjoyed sex - that was the strong impression she gave Paolo.

"She has never revealed the identity of her 'first love', but clearly, at 16 years old, she was already experienced in the ways of pleasing a man.

"For someone so careful about her private life, Kylie can be astonishingly indiscreet. It is as if, every so often, she gets the devil in her," he adds.
